Question

Anaida finishes her homework in $45$ minutes on Suday. On Saturday she need $4$ times that amount of time. How much time does she spend on homework on both days together?

Answer 1

Time taken by Anaida to finish her homework on Saturday $=45$ mins

Time taken by Anaida to finish her homework on Sunday $=45$ mins

Time taken by Anaida to finish her homework on Saturday $=(4\times 45)$ mins

$=180$ mins

Total time spend by Anaida on homework on both days $=(180+45)$ mins

$=225$ mins

$60$ minutes $=1$ hour

$225$ minutes $=\frac{1}{60}\times 225$

$=3.75$ hour

$=3$ hour $45$ minutes

$\therefore$ Total time spend by Anaida $=3$ hour $45$ minutes.
